Qualitative filter paper sheets, Whatman Grade 3
Filter paper made from pure cellulose for general, analytical, and technical filtration of crystalline precipitations and particulates, with slow flow rate. Grade 3 qualitative filter papers are double the thickness of Grade 1 with a slower filtration, but the thickness gives a notable increase in dry and wet strength as well as loading capacity. Used for qualitative analyses and to collect and identify materials in your sample.
